dominator cylinder on xr600 engine

Recommended Posts

hello all, 

i'm looking for a build thread concerning putting a nx650 cilinder on a xr600 engine.

Does anyone know of a build thread here, which includes all the modifications needed.

 

Thank you very much

there are build threads here for an XR650L cylinder on a XR600R..

You`ll have to search,,

 

The XR650L cylinder is the same as the NX.

OK, here is the answer your looking for.

I just did this for a fellow in Italy. He wanted a bigger piston for his XR600. Over here the XR600 has a 97mm bore.

I supplied him with a XR650l 100mm bore cylinder that was bored to fit a JE 101mm piston I got from XR's Only. I chose 101mm in case he ever needed to replace the piston he could go to one of the next size up.

If you buy a NX650 cylinder it will be 100mm and it will need to be bored to a larger size piston.

Wiseco only goes to a 100mm piston for the XR600.

XR's Only lists six pistons to do what you want. They are all around $180.00 to $185.00

One issue is I don't know if they ship out of the country but they may.

Here is what they list on their web site:

Wossner 100.94 and 101.94. No compression ratios stated.

XR's Only (most likely a JE piston) 101mm 10.6 CR and 102mm 10.5 CR

JE 101mm 10.6 CR and 102mm 10.8 CR

I'm not as familiar with the 600R as I am with the 650s , but I would think if the 600 pistons can be used in the 650s , the 650 pistons should work in the 600.

^ NOPE

 

The XR600 and XR650l have different wrist pin to piston crown measurements.

 

Actually you can put a XR600 piston in a XR650l but not the other way around as the piston will be way down in the cylinder. AMHIK... Dammit.
